Sloths can swim! In fact, they can move through the water three times faster than they move on land. That really isn't saying much, so people still rescue "drowning" sloths. The sloths are probably complaining constantly about this misguided altruism, but as they complain so slowly, no one pays attention. -via Arbroath

You can't really blame people for wanting to 'save' a swimming sloth :P heh They get up close to that curious looking floating mat of hair and "Oh look! A sloth!" Come on, who could resist picking it up?
